DETAILED DESCRIPTION

[0030] The present invention is further described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figure 1-Figure 10As shown, the present embodiment provides an electric meter opening and closing module, including a shell 1, a shell cover 2, an opening and closing actuator component 3 and an opening and closing standby component 4, the opening and closing actuator component 3 is installed inside the shell 1, the shell cover 2 is installed on the upper end of the shell 1 through an easily disassembled mounting component 5, the opening and closing actuator component 3 includes an electromagnet 7 with a wiring port 6 at one end, a mounting frame 8, a rotating bracket 9, an L-shaped plate 10, a first copper sheet 12 with a moving contact 11 installed at one end, and a second copper sheet 14 with a static contact 13 installed at one end, the opening and closing standby component 4 is installed inside the shell 1, one end of the opening and closing standby component 4 is connected to the first copper sheet 12, and the other end of the opening and closing standby component 4 is electrically connected to the main board of the electric meter through a wiring terminal, and the electromagnet 7 is fixedly installed in the shell 1. At one end of the body, the mounting frame 8 is fixedly installed in the middle position of the shell 1, the rotating bracket 9 is hinged at one end of the mounting frame 8, and square magnets 15 distributed up and down are fixedly installed on both sides of the rotating bracket 9. Both ends of the electromagnet 7 are attracted to the square magnets 15. One end of the rotating bracket 9 is hinged to the L-shaped plate 10 through the connecting plate 16, and the L-shaped plate 10 is fixedly connected to the first copper sheet 12. A third copper sheet 17 is fixedly installed inside the mounting frame 8, and the third copper sheet 17 is hinged to the first copper sheet 12. The second copper sheet 14 is plugged into one side of the shell 1, and the moving contact 11 is in contact with the static contact 13. When using it, first install the shell 1 and the shell cover 2 inside the smart meter, and the wires at one end of the meter are installed in the connecting holes of the second copper sheet 14 and the third copper sheet 17. The wire is electrically connected to the meter mainboard to detect whether the opening and closing module is working normally. Then, the electromagnet 7 is electrically connected to the meter mainboard through the wiring port 6. When the user owes fees or other unexpected situations occur, the meter mainboard controls the opening and closing actuator 3 to close the gate, thereby cutting off the power to the user. When the user pays again, the meter mainboard controls the opening and closing actuator 3 to close the gate, and the user is powered on. During the closing process, the meter mainboard supplies power to the electromagnet 7 through the wiring port 6. The electromagnet 7 generates magnetism and adsorbs the square magnets 15 on both sides of the rotating bracket 9. At this time, the rotating bracket 9 rotates at a certain angle in the mounting bracket 8, and drives the L-shaped plate 10 to move through the connecting plate 16, and the first copper sheet 12 moves accordingly. The moving contact 11 is separated from the static contact 13 at one end of the second copper sheet 14, thereby completing the closing operation and cutting off the power. When it is necessary to close the switch, the meter mainboard controls the change to the direction of the power supply current of the electromagnet 7, and the magnetic poles of the electromagnet 7 change accordingly, so that the electromagnet 7 adsorbs the square magnets 15 on both sides of the rotating bracket 9, so that the rotating bracket 9 is reset, and then the L-shaped plate 10 is driven to move in the opposite direction through the connecting plate 16, so that the moving contact 11 on the first copper sheet 12 moves and contacts with the static contact 13 at one end of the second copper sheet 14, and the power is turned on. When the electromagnet 7 or other components fail after long-term use, causing the moving contact 11 and the static contact 13 to loosen, the meter opening and closing module stops working, and the meter mainboard detects that the meter opening and closing module stops working.The switch-on and switch-off spare component 4 controls the meter to open or close the switch, so that the meter can work normally and avoid economic losses. When the components inside the housing 1 need to be repaired, the housing cover 2 can be removed from the housing 1 through the installation component 5, which is convenient for the staff to repair the components inside the housing 1 without the help of other tools, saving time and effort, improving the maintenance efficiency, and also facilitating the installation of the housing cover 2.

When it is used, when it is necessary to disassemble and repair the components inside the housing 1, the sliding plates 501 on both sides of the housing 1 are manually moved inward to make them in the sliding grooves 503 The limit block 508 in the square hole 504 moves inward accordingly, thereby disengaging from the square notch 507 at one end of the square plate 502, thereby releasing the restriction effect on the square plate 502. At this time, the free end of the telescopic sleeve rod 505 contracts, and the spring 506 is compressed. Then the shell cover 2 is manually moved upward to remove the square plate 502, and the positioning rod 19 is disengaged from the positioning groove 18, thereby completing the disassembly of the shell cover 2, and then the sliding plate 501 is loosened, which is convenient for the staff to replace or overhaul the components inside the shell 1. No other tools are required, and the operation is simple. After the overhaul or replacement is completed, the positioning rod 19 is first One end of the rod 19 is placed in the positioning groove 18 to guide and position the shell cover 2, and then the sliding plate 501 is manually moved inward, and then the shell cover 2 is moved downward, and the square plate 502 moves into the square groove. When the shell cover 2 is in close contact with the shell body 1, the sliding plate 501 is released. Under the action of the deformation force of the spring 506, the sliding plate 501 automatically moves in the sliding groove 503, and the limit block 508 moves accordingly and moves into the square notch 507 to fix the square plate 502, thereby completing the installation and fixation of the shell cover 2. At this time, the telescopic sleeve rod 505 is extended to guide and limit the sliding plate 501.

[0033] like Figure 7 and Figure 8As shown, the switch opening and closing standby component 4 includes a first motor 401, a round tube 402 and a round rod 403. The round tube 402 is fixedly installed at one end inside the shell 1, and the round rod 403 is inserted in the round tube 402. A round hole is opened at one end of the first copper sheet 12, and one end of the round rod 403 extends into the round hole. A baffle 404 distributed up and down is fixedly installed at one end of the round rod 403. A cavity is opened inside one end of the shell 1, and a threaded rod 405 is rotatably installed in the cavity. One end of the threaded rod 405 is threadedly connected to the round rod 403, and a gear 406 is fixedly installed at one end of the threaded rod 405. The first motor 401 is fixedly installed inside the shell 1, and a rotating shaft 407 is fixedly installed at the output end of the first motor 401. A rotating plate 408 is fixedly installed at one end of the rotating shaft 407. A T-shaped plate 409 is slidably installed, and a waist-shaped hole 410 is opened at one end of the T-shaped plate 409. A moving rod 411 is clamped in the waist-shaped hole 410. The moving rod 411 is rotatably connected with the rotating plate 408. A rack 412 is fixedly installed at one end of the T-shaped plate 409, and the rack 412 is meshed with the gear 406. When in use, when the electromagnet 7 or other components fail after long-term use, causing the moving contact 11 and the static contact 13 to loosen, the meter opening and closing module loses its function, and the information is fed back to the meter main board through the wire. The meter main board detects that the meter opening and closing module stops working, and supplies power to the first motor 401 through the wiring terminal. The output end of the first motor 401 starts to rotate, driving the rotating shaft 407 to rotate, and the rotating plate 408 at one end thereof rotates in a circle accordingly. The T-shaped plate 409 is moved back and forth periodically by the moving rod 411. At this time, the moving rod 411 moves in the waist-shaped hole 410 at one end of the T-shaped plate 409, and the rack 412 at one end of the T-shaped plate 409 moves back and forth in the cavity accordingly, so that the gear 406 rotates back and forth, and the threaded rod 405 rotates inside the cavity accordingly, so that the round rod 403 moves in the round tube 402, and the first copper sheet 12 is moved by the baffle 404 at one end of the round rod 403, and the moving contact 11 on the first copper sheet 12 moves accordingly to open or close the switch. When it is necessary to open the switch, the first motor 401 is controlled by the main board of the electric meter to rotate half a circle, so as to drive the round rod 403 to move a certain distance outward, and the first copper sheet 12 is driven to move to the lower end through the baffle 404 at the upper end, so that the moving contact 11 on the first copper sheet 12 11 is separated from the static contact 13 to cut off the power to the user. The main board of the electric meter controls the first motor 401 to rotate half a circle and then cut off the power, separating the moving contact 11 and the static contact 13. When it is necessary to close the switch, the first motor 401 is powered by the main board of the electric meter. After the first motor 401 rotates half a circle, the round rod 403 moves inward by a certain distance, and the baffle 404 at the lower end drives the first copper sheet 12 to move to the upper end, so that the moving contact 11 on the first copper sheet 12 contacts the static contact 13, and the power-on state is restored. After the first motor 401 rotates half a circle, the main board of the electric meter automatically cuts off the power to the first motor 401, so that in the process of opening and closing the switch, there is no need for the first motor 401 to rotate forwards and backwards, the structure is simple, the cost is saved, and the electric meter can work normally at the same time.Avoid causing certain economic losses.
